There are three families of leptons;

electron, muon, and pi.
|
|
|
electron, muon, and tau.
|
|
|
electron, pi and tau.
|
|
|
electron, pi and neutrino.
|
Explanation:
Detailed explanation-1: -Leptons are divided into three lepton families: the electron and its neutrino, the muon and its neutrino, and the tau and its neutrino. We use the terms “electron number, ‘’ “muon number, ‘’ and “tau number” to refer to the lepton family of a particle.
Detailed explanation-2: -Amazing fact: all known matter is made of just three tiny particles called up quarks, down quarks and electrons.
Detailed explanation-3: -There are six known leptons, and they occur in pairs, called generations, which we write as doublets: ( e e − ), ( − ), ( − ) . Each generation comprises a charged lepton with electric charge Q = −e, and a neutral lepton or neutrino.
